section of the spuug 51g. A, on on en'- spond q1 block 14 Composed o non-vbrfn motel-iol. preferzfoy Wood, is mounted o top of H10 section 7. the under surface o? i said Hoek being 'provided with yeessses lo imo which t he (1i-oss pieces O. the bos. Upon This ol ek is 'pncefl *ehe uppef secion of oe spring, this secon being pefemby Composed of n less rm'mbel of Temes 'ihm the lowerseeon 7.

The. opper side portions of the H-oots 9 above the erosspeces 10 embrace the opposite sides of chs upper section, :m ther Aetx'emi'es :we reduced and project through perontons formed in reinforcing pate 1G which is moune upon fue uppermost les?" of 'the section S. oss pieces 17 ae te over the upper ememes of the "-bolts end are adapte so es upon the plete 16, sui Cross pieces being heid seom'ely in place by nuts 18, whch a'e applied o the L--bolts ezemes, 'the lait-er being of the spngg' e the e me' identify o the secuveo bloeit im@ leaves Eommg the opper secon.

Wish ii; mestooo'. ooveve, that fio 'noy mt myself the speec fasenng means iscose, since am aware that @ber suabe means may be employee( Without depm'tng om the spirit of mv invention.

nother important feature of my invenion Conssts in of'oiisljf connecting the QX- temtes of the owef section with the nmmo of Fue vehice 2111: mova ijf connecng iks extremes of 'ine upper section W'-h owe seeon.

Hoving briey oeine my imoove Construction, W proceed to desc'fbe 'me same in em, reeence being made "io ih@ accomthreaded for this purpose. These nuts vwhen screwed tightly in place, besides securing the leaves of the upper section 6 together, practically form an integral construction including both sections 6 and 7, the plate 16 and the interposed non-vibrating block 14. These said'eleinents are further secured together by means of a bolt A, the head ot' which tits into a recess B formed in the axle and whose shank extends upwardly through both spring sections, the block and the plate 1G, the upper extremity ot' the bolt having a nut (l screwed thereon which tightly engages the said plate 1G.

It should, however, be especially noted in this connection that the leaves comprising the lower section 7, are fastened tightly together and attached to the front axle 8 independently of the means for securing the plate 1G, block 1l and leaves comprising the upper section t3.

One extremity of the section A'i' is pivotally connected with one extremity of the Vehicle frame t as disclosed at 19, while the` other extremity ot' the said section is pivotally connected as shown at 20, with the lower extremity of a link 21, the opposite extreinity of which is pivotally connected with a bracket 22 secured to the under surface of the frame 4. The opposite extremities of the Section 6 are each pivotally connected with a pair of links 23 which, after the .said section is forced downwardly from its natural position (disclosed by dotted lines in Fig. 1), will straddle the end portions of the lower section 7, after which the lower extremities of the links 23 are connected by pins 24 which are adaptedto engage the said section 7, whereby the extremities of the upper section are inovably connected Y with the end portions of the lower section.

By reason of the block interposed between the spring sections and the manner in which these sections are secured to the axle and -t'rame of the vehicle, the upper section 6 can beso arranged that it will act as a sort y ot' butter, or, in other words, will, to a cer- Attentionv is called to the fact that my improved spring may be employed as the upper or lower half ofian elliptical spring,

vor one of my springs may be employed as the lower half and one as the upper halt` of such a spring, and, furthermore, it may constitute the lower member of a three-quarter elliptical spring.

Also my spring may be mountedupon either the front or rear axle of the vehicle.

Having' thus described my invention, wha't I claim is,- I

1. A vehicle spring composed .of upper and lower sections, a block interposed between the said sections midway of the extremities of the latter, H-bolts for securing the central portion of the spring to the axle of the vehicle, the upper and lower arms of said bolt embracing the upper and lower sections respectively, and cross pieces of the said H-bolts adapted to bear upon the upper surface of the lower section whereby the leaves comprising the latter are independently secured in place.

2. A vehicle spring composed of upper and lower sections, a block interposed between the said sections midway of the eX- tremities of the latter, H-bolts -for securing the central portion of the spring to the axle of the vehicle, the upper and lower arms of said bolt embracing the upper and lower sections respectively, and cross pieces of the said H-bolts' engaging recesses formed in the said block and adapted to bear upon the upper surface of the lower section whereby the leaves comprising the latter are independently secured in place.

In testimony whereof I affix my signature, in presence of two witnesses.
